Hey what I have found funny is this....I have them in with my BIG RedHead Cichlids....I thought because the redheads are a pair and so are the severums that they would keep to themselves. They have caves etc....so my big boy (redhead), he wasn't at all fussed about the new arrivals, my girl, she followed them around for awhile, nothing major. The night went on and they all fed together and seemed just fine (phew), so this afternoon I look into the tank and see male redhead in HIS cave with a severum, girl redhead is not allowed in and the other severum is enjoying lots of space in its own cave lol. Meanwhile the female redhead hangs around wondering what to do with herself lol. Since the new tank mates have moved in my redheads are doing a bit more lip locking than usual too.
